Unable to select channels other than stereo

Hi,

Sorry for the delayed reply, I have been digging through the EDID files with my coworker to verify what I am seeing.

It looks like the audio issue is being resolved by converting this line:

Linear PCM, max channels 2
Supported sample rates (kHz): 192 96 48 44.1 32
Supported sample sizes (bits): 24 20 16

to this line:

Linear PCM, max channels 6
Supported sample rates (kHz): 192 96 48 44.1 32
Supported sample sizes (bits): 24 20 16

Our adapter support LPCM up to 8-channels but does not support the additional formats used by this receiver:

AC-3, max channels 6
 Supported sample rates (kHz): 48 44.1 32
 Maximum bit rate: 640 kHz

Dolby Digital+, max channels 8
Supported sample rates (kHz): 48 44.1 32
MAT (MLP), max channels 8
Supported sample rates (kHz): 48
DTS, max channels 6
Supported sample rates (kHz): 96 88.2 48 44.1
Maximum bit rate: 1536 kHz
DTS-HD, max channels 8
Supported sample rates (kHz): 192 176.4 96 88.2 48 44.1

Most likely the receiver supports LPCM 6 channel but it is not being advertised, the incorrectly matched compatibility is falling back to the lowest common supported feature set, or LPCM 2 channel.

Also interestingly, the EDID shows a lot of modes and options I would not expect to see from this television.

Would it be possible to connect the television directly to the computer and capture the EDID file ( instead of through the receiver )? We can then see if the receiver is injecting additional modes into the EDID.

Thank you,
